Abstract
Wilson’s disease (WD) is an autosomal recessive genetic disorder due to a mutation of the ATP7B gene, resulting in impaired hepatic copper excretion and accumulation in various tissues. Ocular findings are one of the hallmarks of the disease. Many ophthalmological manifestations have been described and new techniques are currently available to improve their diagnosis and to follow their evolution. We have performed a systematic PubMed search to summarize available data of the recent literature on the most frequent ophthalmological disorders associated with WD, and to discuss the newest techniques used for their detection and follow-up during treatment. In total, 49 articles were retained for this review. The most common ocular findings seen in WD patients are Kayser–Fleischer ring (KFR) and sunflower cataracts. Other ocular manifestations may involve retinal tissue, visual systems and eye mobility. Diagnosis and follow-up under decoppering treatment of these ocular findings are generally easily performed with slit-lamp examination (SLE). However, new techniques are available for the precocious detection of ocular findings due to WD and may be of great value for non-experimented ophthalmologists and non-ophthalmologists practitioners. Among those techniques, anterior segment optical coherence tomography (AS-OCT) and Scheimpflug imaging are discussed.

Clin Gastroenterol Hepatol 2021; 19:590-596. [PMID: 32485301 DOI: 10.1016/j.cgh.2020.05.044] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/24/2019] [Revised: 05/17/2020] [Accepted: 05/22/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Wilson disease is an autosomal recessive disorder that impairs copper homeostasis and is caused by homozygous or compound heterozygous mutations in ATP7B, which encodes a copper-transporting P-type ATPase. Patients have variable clinical manifestations and laboratory test results, resulting in diagnostic dilemmas. We aimed to identify factors associated with symptoms and features of Wilson disease from a large cohort, over 15 years. METHODS We collected data from 715 patients (529 with symptoms, 146 without symptoms, and 40 uncategorized) and a genetic confirmation of Wilson's disease (mean age of diagnosis, 18.84 years), recruited from 3 hospitals in China from 2004 through 2019. We analyzed clinical data along with serum levels of ceruloplasmin (available from 636 patients), 24-hr urinary copper excretion (collected from 131 patients), Kayser-Fleisher rings (copper accumulation in eyes, with neurologic data from 355 patients), and magnetic resonance imaging (MRI) abnormalities. Differences among the groups were analyzed using 1-way analysis of variance followed by Tukey multiple comparison test. RESULTS Of the 529 patients with symptoms, 121 had hepatic features, 355 had neurologic features, 28 had osteomuscular features (premature osteoarthritis, skeletal deformities, and pathological bone fractures), and 25 had psychiatric symptoms. Age of onset was significantly younger in patients with hepatic (16.94 ± 1.03 years; P = .0105) or osteomuscular features (13 ± 1.33 years; P = .0001) than patients with neurological features (19.48 ± 0.46 years). Serum levels of ceruloplasmin differed among asymptomatic patients and patients with osteomuscular or neurologic symptoms of Wilson disease. Serum levels of ceruloplasmin ranged from 18.93 mg/L to approximately 120.00 mg/L (quantiles of 0.025 to approximately 0.975). Fifty-one of 131 patients (39%) had urinary copper excretion levels below 100 μg/24 hr; there was significant variation in levels of urinary copper excretion between patients older than 14 years vs 14 years or younger. Of the 355 patients with neurologic features, 244 patients (69%) had abnormal findings from MRI and Kayser-Fleisher rings; only 1 patient with abnormal findings from brain MRI was negative for Kayser-Fleisher rings. CONCLUSIONS Serum level of ceruloplasmin, 24-hour urinary copper excretion, and Kayser-Fleisher rings can be used to identify patients who might have Wilson disease. Patients with serum levels of ceruloplasmin below 120 mg/L and children with urinary copper excretion above 40 μg should undergo genetic testing for Wilson's disease. Patients with movement disorders and brain MRI abnormalities without Kayser-Fleisher rings are not likely to have Wilson disease.

Abstract
PURPOSE Kayser-Fleischer ring pathognomonic for Wilson disease (WD) is formed of corneal copper deposits present predominantly within the anterior chamber angle at the Schwalbe's line. The slit-lamp assessment commonly used as a standard of care cannot detect them early enough, as the angle view is obscured by the corneal limbus. The aim of the research was to evaluate the anterior segment optical coherence tomography (AS-OCT), as objective diagnostic assessment of copper deposits forming KF ring in patients with WD. METHODS Twenty-nine subjects (17 women) and twenty-nine controls (14 women) were enrolled and underwent slit lamp and AS-OCT assessment. RESULTS Kayser-Fleischer ring was not detected - either with a slit lamp or with AS-OCT - in any of the controls. Fifteen subjects presenting without KF ring at a slit-lamp examination were found to have a KF ring when examined with AS-OCT (p < 0.001), which confirms improved accuracy of AS-OCT, as compared to the slit-lamp examination. CONCLUSION Our results support AS-OCT as a diagnostic procedure to offer better objectivity and accuracy as compared to a slit-lamp examination, both at the diagnostic stage and when monitoring changes in KF ring during medical therapy to assess its efficacy and patient compliance.

Abstract
Prion diseases are unique in medicine as in humans they occur in sporadic, genetic, and acquired forms. The most common human prion disease is sporadic Creutzfeldt-Jakob disease (CJD), which commonly presents as a rapidly progressive dementia (RPD) with behavioral, cerebellar, extrapyramidal, and some pyramidal features, with the median survival from symptom onset to death of just a few months. Because human prion diseases, as well as other RPDs, are relatively rare, they can be difficult to diagnose, as most clinicians have seen few, if any, cases. Not only can prion diseases mimic many other conditions that present as RPD, but some of those conditions can present similarly to prion disease. In this article, the authors discuss the different etiologic categories of conditions that often present as RPD and also present RPDs that had been misdiagnosed clinically as CJD. Etiologic categories of conditions are presented in order of the mnemonic used for remembering the various categories of RPDs: VITAMINS-D, for vascular, infectious, toxic-metabolic, autoimmune, mitochondrial/metastases, iatrogenic, neurodegenerative, system/seizures/sarcoid, and demyelinating. When relevant, clinical, imaging, or other features of an RPD that overlap with those of CJD are presented.

Abstract
Wilson's disease (WD), albeit relatively rare, is an important genetic metabolic disease because of highly effective therapies that can be lifesaving. It is a great imitator and requires a high index of suspicion for correct and timely diagnosis. Neurologic, psychiatric and hepatologic problems in WD are very nonspecific, and we discuss the most common clinical phenotypes. The diagnosis remains laboratory based, and here we review the most important challenges and pitfalls in laboratory evaluation of WD, including the emerging role of genetic testing in WD diagnosis. WD is a monogenic disorder but has very high allelic heterogeneity with >500 disease-causing mutations identified, and new insights into phenotype-genotype correlations are also reviewed. The gold standard of therapy is chelation of excessive copper, but many unmet needs exist because of possible clinical deterioration in treated patients and potential adverse effects associated with currently available chelating medications. We also review the most promising novel therapeutic approaches, including chelators targeting specific cell types, cell transplantation and gene therapy.

Abstract
OBJECTIVES Here, we reported our experience over 28 years with 133 cases of patients with Wilson's disease (WD) in order to illustrate the diverse clinical presentation and to improve understanding and early diagnosis of WD. METHODS We reviewed the medical records of patients with WD at Shengjing Hospital of China Medical University from 1993 to 2011. The clinical manifestations and laboratory findings were analyzed. The diagnosis was based on the presence of Kayser-Fleisher (K-F) rings, low serum copper levels, low serum ceruloplasmin levels, increased urinary copper concentrations before or after penicillamine challenge. RESULTS Among them, 93 patients mainly presented with hepatic manifestations, 27 with neural abnormalities, and 13 presented with others. Age range at diagnosis was wide (3-74 years, average 13·2 years), and five patients were over 40 years. The oldest one was aged 74 years and presented with neuropsychiatric disorder. The positive rate of K-F rings was 93·0%. The serum ceruloplasmin decreased in 83·6% patients, 24-hour urinary copper increased in 88·1% patients, and serum copper decreased in 68·9% patients. About 79·7% of patients were diagnosed within 6 months, but only 33·1% were diagnosed at their initial medical consultation. There was a substantial delay of up to 15 years. CONCLUSIONS The clinical manifestation of WD is very diverse and no one feature is completely reliable. Doctors in many fields have opportunities to encounter this disease, and the most important thing is to be aware of the possibility of WD.

Abstract
BACKGROUND Urinary copper excretion higher than 100 μg/24 h is useful for diagnosing Wilson's disease. d-Penicillamine challenge test may produce higher levels than 1400 μg/24 h, allowing for better diagnostic accuracy. This study investigated whether heterozygotes reach this value and compared copper serum levels, ceruloplasmin, and urinary copper excretion before and after administering d-penicillamine to the parents of Wilson's disease patients. METHODS Fifty parents of adult patients were enrolled to obtain copper serum levels and ceruloplasmin along with 24-h urinary copper excretion before and after administering 1g d-penicillamine. RESULTS Serum ceruloplasmin and copper levels were significantly lower in fathers than in mothers (mean 21.8×27.8 mg%; 71.4×88.0 μg%; p ≤ 0.001). The mean of basal 24-h urinary copper excretion was higher in fathers (26.2×18.7 μg/24 h, p=0.01), but did not differ between the genders after d-penicillamine (521.7×525.3, range 31.6-1085.1 μg/24h, p=0.8). CONCLUSIONS The mean values of serum copper, ceruloplasmin, and basal urinary copper excretion were different between males and females. The current diagnostic threshold of 24-h urinary copper excretion after d-penicillamine was not reached by heterozygotes. The increased urinary copper excretion after d-penicillamine challenge was much higher than fivefold the upper limit of normal urinary copper excretion in the majority of heterozygotes and should not be taken into account when diagnosing Wilson's disease.

Abstract
AIM Patients with Wilson disease show complex clinical features. Accurate diagnosis at the initial clinical manifestation is important for patients to receive effective treatment with anti-copper agents. In this study, we assessed whether the international scoring system for the diagnosis of Wilson disease is a reliable tool for screening Japanese patients with primary copper toxicosis requiring anti-copper treatment. METHODS Twenty-three Japanese patients suspected of Wilson disease were enrolled in this study. We performed long-range polymerase chain reaction to detect ATP7B mutations in this series. Finally, we retrospectively assessed the reliability of using a diagnostic score of 4 or more points as the cut-off for this scoring system. RESULTS Ten patients were homozygous or compound heterozygous for ATP7B mutations including a novel mutation of 3837 bp deletion including 3 exons. The mutation would have been missed by the traditional analysis. Six patients were heterozygous for ATP7B mutations. Three of these six patients had additional diagnostic points. The other three patients were diagnosed as carriers of a mutant gene based on their low scores. One of the seven patients free from ATP7B mutation was affected by copper toxicosis. Though the score was 3 points based on increased urinary copper and copper-positive cirrhosis, anti-copper treatment promptly improved liver failure, which was likely due to idiopathic copper toxicosis. CONCLUSION The international scoring system for diagnosis of Wilson disease is a fairly reliable tool for screening Japanese patients who need anti-copper treatment. Caution is needed for patients with possible idiopathic copper toxicosis because the maximal score is 4 points.

Abstract
BACKGROUND AND STUDY AIMS Most paediatric patients with Wilson's disease (WD) present with hepatic manifestations, but some may have neurologic or psychiatric features. Our aim was to define the clinical, biochemical features and the outcome of therapy of a group of Egyptian children diagnosed with WD. PATIENTS AND METHODS The study was carried out at the Paediatric Hepatology Unit at Cairo University Children's Hospital, Egypt; 54 patients were diagnosed with WD from 1996 to 2009. The diagnosis was based on low serum ceruloplasmin levels, increased urinary copper concentrations before or after D-penicillamine challenge and/or the presence of Kayser-Fleischer (K-F) rings. RESULTS The clinical presentation was as follows: hepatic presentation in 33 patients (61%), hepato-neurologic 3 (5.5%), neurologic 5 (9.3%) and presymptomatic 13 (24%). Twelve couples had more than one affected sib. Increased urinary copper concentrations before or after D-penicillamine challenge was found in all patients, low serum ceruloplasmin in 97% and K-F rings in 31.5%. All patients were treated with penicillamine and zinc sulphate except one presymptomatic case who was treated with zinc sulphate only. Three patients underwent liver transplantation and eight patients died after a median duration of treatment of 6 months (1-36). The hepatic symptoms improved with treatment but the neurological symptoms remained stationary. CONCLUSIONS Clinical and biochemical assays remain the standard for diagnosis of WD. Penicillamine and zinc therapy can effectively treat WD with hepatic symptoms. Liver transplantation remains life saving for those with fulminant and end stage WD. Screening for presymptomatic sibs is of utmost importance.

Abstract
Wilson disease (WD) results when specific mutations occur at the ATP7B gene. The presence of mutations in the ATP7B gene was studied in the coding region and the intron-exon boundaries in 15 WD Spanish patients, and their first-degree relatives when possible. A total of 20 nucleotide sequence changes were detected, 18 missense and two splicing mutations. Six of these variants were classified as disease-causing mutations, five missense, and one splicing; four of them have been previously described (M645R, A1065P, H1069Q, and 3060 + 5G > T), whereas two were novel (P768L and A990P). No mutation was clearly prevalent, although the H1069Q mutation predominated, nor did a good phenotype-genotype correlation exist. The two new mutations described were manifested as an asymptomatic increase in serum transaminases. The remaining 14 changes were classified as polymorphisms and their potential effects on protein function are discussed. The identification of mutations in the ATP7B gene has allowed a conclusive diagnosis to be made of WD in patients presenting neurological phenotype or neurological of hepatic phenotype, who would otherwise not have been diagnosed using classical criteria. WD patients could start chelating treatment earlier on and possibly modify the natural progression of the disease.

Abstract
BACKGROUND Wilson's disease (WD) is a treatable autosomal recessive metabolic disorder which could lead to protean hepatic or neurologic manifestations. WD could mimic many neurologic disorders and is often diagnosed with a long delay. This study describes central nervous system manifestations of a group of Iranian patients with neurologic WD. METHODS Data from case records of patients with neurologic WD presenting at a referral university hospital and a private clinic in Tehran from 1984 to 2004 were analyzed. RESULTS Fifty patients from 44 unrelated families with WD were identified, whose mean duration of follow-up was 51.8 (+/-58.5) months. The median age of onset of neurologic symptoms in 37 patients with primary neurologic or simultaneous hepatic-neurologic presentation was 16 (10-38) years, whereas in 13 patients with prior hepatic damage, this was 18.5 (11-34) years. The 6 most common manifestations were dysarthria (80%), drooling (48%), tremor in limbs (44%), abnormal gait (44%), psychiatric and/or sleep symptoms (44%), and dystonia in limbs (42%). CONCLUSION Neurologic WD has heterogeneous manifestations and should be considered in young patients presenting with dysarthria, drooling, any kind of movement disorders or psychiatric symptoms.

Abstract
Dystonia is a movement disorder with many presentations and diverse causes. A systematic approach to dystonia helps to ensure that patients with this disorder receive optimum care. This Review begins with a summary of the clinical features of dystonia, followed by a discussion of other disorders to be considered and excluded before assigning the diagnosis of dystonia. Next, we emphasise the importance of classifying dystonia along several dimensions, and we explain how doing so aids in narrowing the differential diagnosis. The more common forms of dystonia are discussed in detail. Finally, we describe how to apply the clinical information for selection of appropriate laboratory investigations.

Abstract
Wilson's disease is an autosomal recessive inherited disorder of hepatic copper metabolism resulting in liver disease and/or neuropsychiatric disease. The diagnosis of neurological disease is straightforward if the following symptoms are present: Kayser-Fleischer rings, typical neurological symptoms and low serum ceruloplasmin levels. The diagnosis is more complex in patients presenting with liver diseases. None of the commonly used parameters alone allows a diagnosis with certainty. A combination of various laboratory parameters is necessary to firmly establish the diagnosis. In the future, limited mutation analysis may play an important diagnostic role. Recently, a group of international experts has proposed a score based on a variety of tests and clinical symptoms. The validity of this score needs to be assessed prospectively. Treatment requires life-long administration of copper chelators (d-penicillamine, trientine). A frequently used alternative is zinc. None of these treatments has been tested by prospective randomized controlled studies. Liver transplantation is reserved for severe or treatment-resistant cases with advanced liver disease, whilst experience with refractory neuropsychiatric disease is limited.

Abstract
PURPOSE Wilson's disease is characterized by neuropsychiatric symptoms with frequent extrapyramidal and intellectual presentations. They have an insidious evolution that leads to a late diagnosis and less therapeutic effectiveness in the advanced forms. METHODS We report 21 cases of Wilson's disease with neurological complications, emphasizing clinical semiology, diagnostic means and problems of the therapeutics in our country. RESULTS The average age at the beginning of the disease was 17.6 years, with a female prevalence (8/13). The signs at first were mostly all neurological (71.4%), then psychiatric (19%) or hepatic (19%). The most common neurological signs were dystonia of members (81%), dysarthria (76%), tremors (76%) or disorders of motoricity (71.4%). Sometimes there were sialorrhea or disorders of the handwriting. The Kayser-Fleischer ring was present in 19 patients. Eighteen patients had clinical and/or biological hepatic involvement. The diagnosis was confirmed by biochemical examinations, which found a low rate of copper in blood, a sinking rate of ceruloplasmin and a very high rate of urinary copper. The cerebral computer tomography shows a cortical and/or subcortical atrophy (37%), and/or a low density of the central grey cores (35%). The treatment was based on D-penicillamine and/or zinc sulfate, according to the availability of the drugs. The evolution was favourable among 18 patients (85%) and not good in 42.8% of the cases. Six of the first patients had poor evolution after many years of follow-up. Finally, only 12 patients (57%) had a very good outcome. The family investigation made among 17 patients revealed 13 family cases. The only predictive factor of a poor evolution was the therapeutic noncompliance (P = 0.006). CONCLUSIONS The neurological presentations are traditional during the Wilson's disease, but are often ignored. We must suspect the disease in children when faced with disorders of handwriting or school failures and in the adult, when faced with neurological symptoms in a patient having a hepatic disease. We must not hesitate to consider it even given purely psychiatric signs, and we had better know to seek the neurological ones.

Abstract
Wilson disease (WD) is an autosomal recessive disorder of copper metabolism. The H1069Q mutation in exon 14 of ATP7B is far the most frequent in Wilson patients of European origin. Mutations in exon 8 and 15 are also common among the over 150 described mutations in the WD gene. The aim was to investigate the frequency of these common WD gene mutations in Hungarian patients. A total of 42 patients with WD from 39 Hungarian families were examined. The H1069Q mutation was assessed by a seminested polymerase chain reaction (PCR)-based restriction fragment length polymorphism (RFLP) assay, while mutations in exons 8, 13, 15, and 18 of WD gene were identified by sequencing. In addition, haplotype analysis was performed using three common microsatellite markers (D13S314, D13S301, D13S316). The H1069Q mutation was found in 27 patients (64.3%). Nine patients were H1069Q homozygous. Eighteen patients were H1069Q compound heterozygous, two of them had H1069Q/P969Q and one patient H1069Q/3400delC genotype. In two of the 15 H1069Q-negative patients a novel mutation in exon 13 (T977M) was detected. One H1069Q-negative patient had a mutation in exon 8 (G710S). None of the studied mutations was detected in 12 WD patients. H1069Q-positive patients from various European countries had the same haplotype pattern. The H1069Q point mutation is frequent in Hungarian patients with WD and appears to have originated from a single founder in Eastern Europe. In contrast, mutations in exons 8, 13, 15, and 18 are uncommon in Hungarian WD patients.

Abstract
The differential diagnosis of PD includes other neurodegenerative disorders; hereditary disorders; and symptomatic causes, such as structural lesions, infections, metabolic abnormalities, hydrocephalus, and drugs or toxins. A good history of symptom evaluation, drug use, and family illness is just as essential as a careful neurologic examination when evaluating a patient with parkinsonism. Although there is no definitive diagnostic test for PD at this time, tests to rule out other causes should be considered and then treatment started.

Abstract
Wilson disease is a recessively inherited disorder of copper transport. Clinical features are highly variable, with any combination of neurological, hepatic or psychiatric illness. The age of onset varies from 3 to 50 years of age. Diagnosis is challenging because no specific combination of clinical or biochemical features is necessarily definitive. The genetic defect is due to a variety of abnormalities in a copper-transporting membrane ATPase. Most of the more than 80 mutations are present at a low frequency, and mutations differ between ethnic groups. At least two mutations are sufficiently common to aid in rapid diagnosis, in European and Asian populations respectively. Molecular analysis can provide a definitive diagnosis for asymptomatic sibs. Treatment, using chelating agents or zinc, is most effective when started before permanent tissue damage occurs.

Abstract
Wilson's disease is an autosomal, recessive-inherited disorder of impaired biliary copper excretion that results in the accumulation of copper in various organs including the liver, the cornea and the brain. The Wilson's disease gene on chromosome 13 codes for a copper transporting P-type ATPase-ATP7B. More than 60 mutations of this gene have been described. The diagnosis of Wilson's disease is based on clinical findings and laboratory abnormalities and can be made if two of the following symptoms are present: Kayser-Fleischer rings; topical neurologic symptoms; and low serum ceruloplasmin levels. In less typical cases diagnosis requires various other tests of copper metabolism. Effective medical treatment with copper chelators (D-penicillamine, trientine) or zinc results in symptomatic improvement and normal life expectancy. Orthotopic liver transplantation is indicated in advanced cases with hepatic decompensation or in patients with fulminant Wilson's disease.
